Ceramide 1

TL;DR. It is a barrier-supporting and skin-conditioning lipid that helps reinforce the stratum corneum lipid matrix and reduce transepidermal water loss. In hair care, it can support cuticle feel and conditioning.

What does Ceramide 1 do in a cosmetic formula?

It is a barrier-supporting and skin-conditioning lipid that helps reinforce the stratum corneum lipid matrix and reduce transepidermal water loss. In hair care, it can support cuticle feel and conditioning.

Is Ceramide 1 clean?

It has a strong clean-standard profile because it is a skin-identical barrier lipid used at very low levels with low sensitization concern. The main review points are source documentation and residual solvents or antioxidants in the supplied blend.

Is Ceramide 1 sustainable?

Commercial grades are commonly made through biotechnology and chemical coupling from plant-derived fatty materials, though supplier routes vary. It is expected to be biodegradable as a lipid, and its low use level limits formula-level footprint.

Is Ceramide 1 COSMOS-approved?

It can be permitted in COSMOS-natural formulations when the commercial grade is made from approved natural or biotech feedstocks and compliant processing. Fully synthetic or animal-derived grades may not qualify, so alignment is supplier-specific rather than automatic.

How does Ceramide 1 work chemically?

The molecule is a long-chain amide lipid built from a sphingoid base and an esterified omega-hydroxy fatty acid, giving it very low water solubility and strong lamellar-structure behavior. It is commonly used around 0.001 to 0.5%, often delivered in pre-dispersed blends with sterols, fatty acids, emulsifiers, and antioxidants because the unsaturated lipid portion can oxidize.
